Am I still A MONSTER

When Lucy was a young child she unconsciously killed people and one day she killed Layla her mother and when Her "father" Jude found out he abused her after Layla's death, Lucy got a letter one day from her mother telling her to run away from the mansion and that her powers were sealed and that she couldn't hurt anyone until she controlled it the seal only lasts until she felt at home with others like she had a new family so her mother told her to go to Fairy Tail to unlock her powers when she came to FT everyone wondered how strong she really is she was scared so she didn't let anyone touch her .....except one person Gajeel ( remember when Gajeel was a shadow iron dragon in the GMG well that's why he could touch her because he is a monster)because he wasn't afraid of her powers but was quite interested in her personality and saw Lucy for herself. Will her powers unlock? Will she kill anyone? Will she fall for Gajeel? Or will she Leave and not come back to him?
